Precision Tunneling Modification for Isolated Cairo’s Recession Type-1 Coverage in Lower Anterior Teeth: A Case Report

Gingival recession is a common mucogingival deformity associated with aesthetic concerns, dentinal hypersensitivity, root caries and plaque retention. Among the various root coverage procedures, the tunneling technique combined with connective tissue graft (CTG) has gained popularity due to its minimally invasive nature and superior aesthetic outcomes. This case report describes the management of an isolated Cairo’s Recession Type-1 (RT-1) in relation to a mandibular incisor using a microsurgical tunneling approach with CTG and root biomodification using 17% EDTA. Complete root coverage with excellent tissue integration and colour harmony was achieved. Preservation of interdental papillae, enhanced vascularity, and reduced surgical trauma contributed to predictable healing. This report highlights the clinical effectiveness of microsurgical tunneling with CTG as a reliable treatment modality for isolated gingival recession defects.
